Hello, Planet Python!

Planet Python is now syndicating the posts about Python of my blog. Thanks to the project maintainer Bruno Rocha for letting me join.

You may think of Planet Python as the all-you-can-eat source of Python content.


It’s an aggregator of dozens of blogs, podcasts, and other resources on the Python programming language. It syndicates posts that cover Python or are of interest to the Python community. Planet Python is a terrific resource for learning the language and keeping up with what’s going on in its ecosystem. I highly recommend that you subscribe to the RSS feed of Planet Python.

If you’re reading this on Planet Python, hi there!

About me I’m Paolo Amoroso, an Italian astronomy and space popularizer, a Google expert, and a podcaster. I’m a Python beginner as I started learning the language in December 2018. But I have been a hobby programmer since the home computer revolution of the early 1980s. And I have always had a soft spot for programming languages, paradigms, and compilers.

Spotting Satellites With Google Street View

See A Satellite Tonight is an app for showing where to view artificial satellites in the sky with the naked eye.


The app simulates the motions of satellites across the sky by overlaying them to a Google Street View panorama. This makes it straightforward to spot satellites, especially for users with no space or astronomy background. During a pass you can see where the satellite is in the sky at your location with respect to landmarks and buildings you are familiar with.

It’s a brilliant twist on an ephemeris interpretation problem. Most apps for showing the positions of satellites or predicting passes give guidance through astronomical references such as star charts, the horizon, or coordinates.

Googler James Darpinian developed See A Satellite Tonight. It’s a web app designed to work on both the desktop and mobile devices, such as with Chrome on Android.

The app has a few limitations. For example, you can’t select arbitrary satellites but only the ones with a ground track close to you…
